When I saw this DaysAgo Timer at ThinkGeek, I could not help but think of george carlin's "Ice Box Man" routine where he talks about how people avoid the whole task of cleaning out their fridge. Mainly because you don't want to deal with how gross the stuff has become.

The DaysAgo timer can help avoid such nasty incidents. By sticking one of these handy dandy reusable timers on your items as they go in the fridge, you can track how many days-or hours-an item has been in there. When you want to reuse the timer, put it on the new items, and hold down the button to reset the timer.

It's a simple, elegant, and relatively cheap solution.
